iaik.security.cipher.AESCBCCMac256KeyGenerator

public class AESCBCCMac256KeyGenerator
extends VarLengthKeyGenerator

This class provides the functionality of KeyGenerator for generating keys to be used with the AESCBCCMac256 authenticated encryption cipher as defined by the BSI Technical Guideline TR-03109-1.

An AES-CBC-CMAC key represents the concatenation of cipher (encryption) key and MAC key (see TR-03109-1): Key = Key_enc||Key_MAC. Thus keys generated by this key generator are 512 bits long: the first 256 bits represent the cipher (encryption) key, the second 256 bits represent the MAC key:

 KeyGenerator keyGen = KeyGenerator.getInstance("AESCBCCMac256");
 SecretKey key = keyGen.generateKey();
